(My plan is to eventually have all the functionality relevant Javascript in the alue codebase instead of template codebase, but that should not stop you from doing whatever you feel is necessary – I can always move them over once the support for that is there.)

(By the way, I have been looking into using jQuery in the functionality related Javascript. It may be a good idea for you to investigate it as well, if you do functionality related JS stuff.)

On the assumption that you're eager to work on the AJAX part, I'm assigning this to you. As I said, I expect that the server side support is already there.

By the way, you should see about getting a local installation of Alue, for two reasons: 1) easier to test templates without having to publish all the attempts and 2) once functionality related Javascript is moved to the Alue code, you need it to be able to test AJAX code.
